Category: Metal

Metal is a category of materials characterized by their high electrical and thermal conductivity, malleability, ductility, and metallic luster. Metals are typically solid at room temperature (with the exception of mercury) and are known for their ability to reflect light. They often have high density and a high melting point. Metals can conduct heat and electricity efficiently, making them ideal for a variety of applications, including electrical wiring, construction, and manufacturing.

Chemically, metals tend to lose electrons and form positive ions, leading to metallic bonding, where atoms share electrons in a “sea of electrons.” Common examples of metals include iron, copper, aluminum, gold, and silver. Furthermore, metals can be categorized into various groups, such as ferrous (containing iron) and non-ferrous metals (like copper and aluminum), and are often alloyed to enhance specific properties, such as strength and resistance to corrosion. In summary, metal refers to a diverse group of elements and compounds that exhibit unique physical and chemical properties, playing a crucial role in industry, technology, and everyday life.
